6mm hex head bolts

Metal expansion nuts, often referred to as expansion anchors or expansion inserts, are specialized fasteners that expand when a bolt or screw is threaded into them. They typically consist of a cylindrical body with slits along its length or an expandable design that facilitates outward expansion. The main purpose of these nuts is to create a secure grip within a substrate, such as concrete, wood, or metal, thereby preventing loosening due to vibrational forces, temperature fluctuations, or stress.

A wafer head self-drilling screw, as the name suggests, is designed with a flat, thin, and round head that closely resembles a wafer. This design not only ensures a flush finish but also provides a broad surface area, distributing load evenly and reducing the chances of material splitting. The unique feature that sets it apart from conventional screws is its self-drilling capability. Equipped with a sharp point and specialized threads, these screws can penetrate through metal, wood, or plastic without the need for a pre-drilled hole, saving time and effort.
